The Red King and The Gun King

The Red King is the most wanted man in the world, he's killed more people for sneezing near him, then he has for them doing wrong by him. he's ruthless, not caring, and the one thing that his members hate is that when he kills he doesn't blink or flinch, some says he has no emotions. No one wants to double cross him, no one ever tries except for one person, the one person he always wants to kill. THE GUN KING.....
The Gun King is the second most wanted an in the world, although he dark and a killer, but he also funny and he love to pull pranks, he has his moments especially when he's messing with the man that hates him the most, his men thinks he's crazy for messing with this man but they don't know the truth behind these to men.

Who will kill who in the end? Who tips the scale? When will the truth come out? What will happen to them two men?
